석탄첨가물Coal additive

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제1도는 석탄애쉬(ashes)에서 측정된 황 억류와 연소된 석탄에서 황에 대한 칼슘의 몰비 사이의 연관성을 보여주는 ASTM애쉬자료의 도면이다. 제2도는 낮은 NOx/SOx버너에서 연소된 아역청탄에 대한 CaO/AL2O3/SiO2의 삼각좌표이다. 제3도는 낮은 NO(SO(버너에서 연소전 및 연소후의 역청탄에 대한 CaO/AL2O3/SiO2의 삼각좌표이다.Figure 1 is a plot of ASTM ash data showing the association between the sulfur capture measured in coal ashes and the molar ratio of calcium to sulfur in the burned coal. FIG. 2 is the triangular coordinates of CaO / AL 2 O 3 / SiO 2 for burned sub-bituminous coal in a low NO x / SO x burner. FIG. 3 is a triangular coordinate of CaO / AL 2 O 3 / SiO 2 for low NO (SO 2 (before burning and after burning in a burner).
